Notes as recorded

The JDMBUYSELL file gives 1969-1973; ja.wikipedia says the domestic 240Z range was announced 20 October 1971 and sold from November 1971, and the 240Z series was discontinued at the April 1973 change. HS30 also covers export right-hand-drive 240Z built from 1969, so a plate dated before November 1971 may be an export car. No catalog confirmation found.

Read this before you rely on the dates

The sources for this row disagree, so treat both dates as approximate until the car’s own plate settles it.

“Notes as recorded” above says what each source gives and where they part.

US import eligibility

Worked out from the dates above, as of November 13, 2026 (PT). Eligibility is decided by the specific car’s build date on its plate.

The two age lines 年式
First builds turn 25 NHTSA, 49 CFR 591.5(i)
Nov 1996
Last builds turn 25 NHTSA, 49 CFR 591.5(i)
Apr 1998
First builds clear 21 years EPA Form 3520-1, code E
1992
Last builds clear 21 years EPA Form 3520-1, code E
1994
Status today 2026-11-13
Every build is past 25 years

The 25-year line is the NHTSA age exemption for a vehicle not built to the Federal Motor Vehicle Safety Standards (49 CFR 591.5(i)), counted from the date of manufacture. The 21-year line is the EPA exemption on Form 3520-1, counted by calendar year and limited to a car in its original configuration.

Eligibility is decided by the specific car’s build date on its plate, not by the chassis code and not by the model year. Two cars of the same code can sit on different sides of the line.

The form opens the eligibility check with this code filled in. General information, not legal advice.
